Checking Brake Fluid - Tesla Model S Owner's Manual

Fluid Reservoirs

Checking Brake Fluid

Warning: Contact Tesla immediately if
you notice increased movement of the
brake pedal or a significant loss of brake
fluid. Driving under these conditions can
result in extended stopping distances or
complete brake failure.
The Brake indicator on the
instrument panel alerts you if the
quantity of fluid in the brake
reservoir drops below the
recommended level. If it displays
while driving, stop as soon as safety
permits by gently applying the
brakes. Do not continue driving.
Contact Tesla immediately.
Fluid Level Check
Tesla checks the brake fluid level at the
regularly scheduled maintenance intervals. To
check it yourself, park Model S on level
ground. When Model S is cool, remove the
maintenance panel (see
Maintenance Panel on page 123).
Check the fluid level visually by looking at the
outside marks on the side of the reservoir
without removing the filler cap.
The brake fluid level should always be
between the MIN and the MAX marks.
Note: Although brake fluid level drops slightly
during normal use as a result of brake pad
wear, it should not drop below the MIN mark.
Topping Up the Brake Fluid
Do not top up your brake fluid. Tesla service
does this when you bring Model S in for
regular servicing. The following instructions
are provided for information purposes and
future reference only:

Removing the
1. Clean the filler cap before removing to
prevent dirt from entering the reservoir.
2. Unscrew the cap and remove.
3. Top up the reservoir to the MAX mark
using brake fluid meeting DOT3 or DOT4
specifications.
4. Replace the filler cap.
Warning: Only use new fluid from a
sealed air-tight container. Never use
previously used fluid or fluid from a
previously opened container—fluid
absorbs moisture which decreases
braking performance.
Warning: Brake fluid is highly toxic. Keep
containers sealed and out of the reach of
children. In the event of accidental
consumption, seek medical attention
immediately.
Caution: Brake fluid damages painted
surfaces. Immediately soak up any spills
with an absorbent cloth and wash the
area with a mixture of car shampoo and
water.
